This thesis focuses on the Hadrianic Aqueduct, a project by the Roman Emperor Hadrian for the water supply of the Roman Athens. It is an underground tunnel approximately 20km long, which starts from the foot of Mount Parnitha and it runs through the Municipalities of Acharnes, Metamorfosi, Irakleio, Amarousio, Chalandri, Filothei- Psychiko and Athens. The Hadrianic was suppling with water the city of Athens for almost 2000 years and it was ending up in the reservoir of Lycabettus, at Kolonaki square.
Today, some authorities are trying to restore it and preserve it, in order to be able to function again and as it is an archeological monument.
Besides its archeological value and its original use, what else can such a majestic project of the past add to the city of today? What is its value to the modern Athens and how it can be part of our reality? The answers to those questions can be found in the interventions designed for the areas that the main tunnel of the aqueduct is passing through. In order to connect the past with the present an interpretationof an architectural element of the Hadrianic Aqueduct is being conducted.
